In article number 1805710 , Yang Tan, Feng Chen, and co‐workers demonstrate that the surface‐enhanced Raman scattering performance of a WSe 2 monolayer can be enhanced via tailoring the atomic ratio of WSe 2 ; this correlates to the exciton and charge‐transfer resonances. For an atomic ratio of 1.96, the maximum enhancement factor on irradiated WSe 2 is more than 120, which is enhanced by more than 40 times compared with pristine WSe 2 .
